A new 13C/1H endorectal coil was designed, 3D printed, and manufactured with optimal dimensions to improve the comfort and tolerability for patients and provide higher SNR over the original endorectal coil used for over a decade. After bench and phantom tests, the new endorectal coil was applied in patient studies for mpMRI-TRUS guided fusion prostate biopsies with hyperpolarized C-13 pyruvate molecular imaging in three patients on active surveillance. The results of this novel approach with the new 13C/1H coil provides an increase in sensitivity, image quality and ultimately supports better detection of lesions.
